We would like to estimate a relationship between the weight of a car (weight) and the miles-per-gallon rating (mpg).

lmpg  - the natural logarithm of mpg

lweight - the natural logarithm of weight

Three models are estimated.

Estimate the MPG rating for a car that weight 2500 pounds using the log-log model.
